L-N-Carbobenzoxy-glutaminsaeure-α-benzylester-γ-cyanmethylester, also known as Z-Glu(OBzl)-CH2CN, is a synthetic peptide derivative that plays a significant role in peptide synthesis. L-N-Carbobenzoxy-glutaminsaeure-α-benzylester-γ-cyanmethylester is a protected form of glutamic acid, where the α-carboxylic group is benzyl-protected, and the γ-carboxylic group is cyanomethyl-protected. The N-carbobenzoxy (Z) group is used to protect the amino group, which is crucial for preventing unwanted side reactions during peptide bond formation. This specific chemical structure is essential for the stepwise assembly of peptides, as it allows for the controlled addition of amino acid residues while maintaining the integrity of the growing peptide chain. The benzyl and cyanomethyl protecting groups are later removed under specific conditions to yield the desired peptide sequence.

4821-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4821-76-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.Calculate Digit Verification of CAS Registry Number 4821-76:
(6*4)+(5*8)+(4*2)+(3*1)+(2*7)+(1*6)=95
95 % 10 = 5
So 4821-76-5 is a valid CAS Registry Number.
